Can magnetism propagate through open space?

Is magnetism like radiation in which there is particle such as photons that carry it through space?

Magnetism refers to the positive and negative charges of particles right? And there attraction and repulsion effects correct?

So if have an empty universe with a negative charge particle one light year away from a positive charged particle, will they attract each other across the empty space?

The proper term is electromagnetic. Yes, electromagnetism propagates through space - witness telecommunication satellites, witness the Earth's magnetic field.

Be careful about assigning particles. Light travels at the speed of light in a vacuum. Objects with mass cannot reach the speed of light. In a sense, the photon as a particle does not exist until light interacts with something.

Magnetism does not refer to the charge of a particle. Those are two separate properties.

When dealing with electromagnetism and the effects, the inverse square law applies. Using an analogy, if you stomp your foot the force might be noted if you are standing on a suspended hardwood floor, but the chance of it being noted in China is so small as to be meaningless. Attraction between particles a light year apart would be orders of magnitude more small.

Is magnetism and electromagnetism different?

What about the positive/negative charge? Do they only repel or attract if touching each other?

The visual of the wave is usually the electric component of the wave going up and down, and the magnetic force represented as going side to side.

If you run a current through a wire, it will generate a magnetic field.
If you run a wire through a magnetic field, it will generate electricity.

The two are obviously related. Rather then my answering questions haphazardly, it would be better if you read a basic electricity book or explanatory website. It is possible to have to unlearn assumptions if the principles are not taught in sequence.




Define "touch." Electron clouds are areas where there is a charge, but at any point in time and space an electron may or may not be there. Here, you might do better with a basic chemistry book and learning about valences and bonds.

When I say touch, I mean the particles come into contact with each other. So for opposite charges they touch and stay together, for same charges they touch and repel each other.

And you mention something about Earth's magnetic field. Is it basically a rope of electrons that get whipped out into space beyond the atmosphere?
